What is what does a side hug mean from a guy?

As an AI language model, I don't have personal experiences or feelings. However, I can provide general information that a side hug is a friendly hug where the person's arms are wrapped around the other person's waist or shoulder without any intention of intimacy. When a guy gives a side hug, it usually means that he cares for the person and wants to express gratitude, comfort, or support. It can also indicate that the guy is being respectful of the other person's personal space or cultural/religious norms that discourage physical touch. Overall, a side hug is a gesture of affection that conveys warmth and positivity without being too intimate or awkward.
